The invention provides a highway 
video monitoring system. The 
video monitoring system comprises a plurality of cameras, a video convergence 
processing platform, a cloud service platform and a 
client,the plurality of cameras transmit acquired videos to the video convergence 
processing platform in real time. The video convergence 
processing platform processes the acquired multiple paths of real-time videos and then sends the videos to the cloud service platform 
system for storage, and after the 
client sends a video playing request to the 
web service node, the 
web service node obtains a video 
stream from the cloud service platform and sends the video 
stream to the 
client for playing. According to the invention, the technical problem of large 
data delay of the existing expressway 
video monitoring system is solved, video-on-demand can be carried out on the video data according to the required definition, the code 
stream can be multiplexed, the use of network bandwidth is reduced, the 
network performance is improved, a scheduling 
algorithm of convergence service nodes and 
server nodes is provided, the technical problems of inflexible scheduling and unbalanced load are solved, and the system performance is improved.
